RFE: dnsbl-support for dovecot
by Reindl Harald 17 Jun '14

17 Jun '14

after having my own dnsbl feeded by a honeypot and even mod_security supports it for webservers i think dovecot sould support the same to prevent dictionary attacks from known bad hosts, in our case that blacklist is 100% trustable and blocks before SMTP-Auth while normal RBL's are after SASL i admit that i am not a C/C++-programmer, but i think doing the DNS request and in case it has a result block any login attemt should be not too complex setup a own honeypot and feed rbldnsd with the sources is quite easy and in case of a own, trustable RBL where no foreigners report somebody by mistake it's relieable and scales well over many machines and services as long services supporting it mod_security: http://blog.inliniac.net/2007/02/23/blocking-comment-spam-using-modsecurity…

[Dovecot] Replication with virtual users and static userdb possible ?
by deano-dovecot＠areyes.com 17 Jun '14

17 Jun '14

Is it possible to get replication working in a virtual user setup that uses a static userdb ? My environment is fairly simple and typical - there's a single system user (vmail) that owns all the home dirs (/var/mail/domain.com/user). The virtual users (userid@domain.com:secretpassword) are kept in a single file (/var/mail/domain.com/PASSWD) that's unique per domain, and referenced as a static userdb : passdb { driver = passwd-file args = scheme=plain username_format=%u /var/mail/%d/PASSWD } userdb { driver = static args = uid=vmail gid=vmail home=/var/mail/%d/%n } I know the wiki http://wiki2.dovecot.org/Replication states that user listing must be enabled, but that's not available for a static userdb. The wiki http://wiki2.dovecot.org/UserDatabase/Static also says that it shouldn't be a problem because it will use do a passdb lookup instead (except for PAM which isn't used here). Unfortunately, it's not working. I've testing with ssh : dsync_remote_cmd = ssh -l vmail %{host} doveadm dsync-server -u%u -l%{lock_timeout} -n%{namespace} mail_replica = remote:vmail@server2.domain.com as well as with straight tcp (SSL for later) mail_replica = tcp:server2.domain.com:999 /var/log/mail.err shows the problems ... Jun 3 11:30:53 server1 dovecot: auth: Error: Trying to iterate users, but userdbs don't support it Jun 3 11:30:53 server1 dovecot: replicator: Error: User listing returned failure Jun 3 11:30:53 server1 dovecot: replicator: Error: listing users failed, can't replicate existing data Anyone else have it working ? I'm sure it's something simple that I've just overlooked. Thanks - D.

Accessing a user mailbox from another user
by Angel L. Mateo 17 Jun '14

17 Jun '14

Hello, I'm looking for something maybe similar to master password but for final users and I don't know if there is already a way I could do it with dovecot. I have accounts that are used by a set of users who know their password. But I now want to remove this shared password and the users has to access to this shared account with their own password. Using shared folders is not an option (at least, not the first option) because of the behaviour our users are familiar with, such as: * They have and manage different sieve filters for the account * They have thier own Sent, Drafts, SPAM... for this shared account and their email client recognizes them as it (because they have its own account). What I'm looking for is something similar to master password, but for a user identifying as another regular user, not the "master" one. Do you know if there already is a way to configure a similar behaviour? I'm planning to configure an user and authentication backend (maybe pam) that gets users as <realuser>$<finaluser> and the realuser password, checks if <realuser> should access to <finaluser> and then returns <finaluser> mail location to dovecot.

Procmail wiki text -- don't muck with SENDMAIL
by era eriksson 16 Jun '14

16 Jun '14

I tried to edit http://wiki2.dovecot.org/procmail but got stuck on the TextCha. Approaching this list instead seems to be a time-tested secondary approach, and I wasn't completely comfortable making these changes without discussion anyway. So here goes. The SENDMAIL= assignment is not only irrelevant, but actually wrong. The note down in the update section about Ubuntu explains the problem well enough, but it applies to all the sections on the page. My proposed edit was to simply remove SENDMAIL and SENDMAILFLAGS from all the recipes on the page, and then remove the Ubuntu section altogether, because it would no longer add anything useful to the page. If somebody in the Dovecot community with edit access to the wiki wants to implement this change, I would be grateful on behalf of the people who try to use Procmail with Dovecot. -- If this were my real .signature, it would suck less. Well, maybe not.

connection to director (lmtp) time out
by Patrick Westenberg 16 Jun '14

16 Jun '14

Hi all, I'm running two directors with lmtp proxy as relay transport for my mail exchangers. relay_transport = lmtp:inet:dovecot-directors.example.net dovecot-directors.example.net resolves to 172.17.1.3 and 172.17.1.4 Now, .3 is down and Postfix tries to deliver it to .4 but this connection gets a timeout: (delivery temporarily suspended: connect to 172.17.1.4[172.17.1.4]:24: Connection timed out There is no log entry on the director. Can anyone give me a hint how to solve this or maybe optimize my configuration?

[Dovecot] Pigeonhole and dsync replication not replicating 'SETACTIVE' for a sieve script
by Skeffling 16 Jun '14

16 Jun '14

Hello, I'm testing dovecot replication alongside pigeonhole and liking it. Dovecot v2.2.13 Pigeonhole v0.4.3 If I create or edit a sieve script on one server (via managesieve, using the thunderbird plugin as it happens) then it does get replicated to the other - great! However, if I set a script to be active (SETACTIVE) on one side then this is not being replicated across to the other server. Is this a known issue? Thank you! -- Andrew

[Dovecot] Outlook 2007 & 2010 hangs in v2.2?
by Timo Sirainen 15 Jun '14

15 Jun '14

Has anybody noticed Outlook 2007 & 2010 (but apparently not 2013) hanging IMAP connections with Dovecot v2.2 (but not v2.1) when they're FETCHing large mails? I can't think of any reasonable explanation for this.
